EMI2.1
Büchse j (Fig. 3).
Der Schneidkopf B kann in üblicher Weise mit Einrichtungen zur Bearbeitung in zwei Abschnitten (Feinschnitt und Grobschnitt) und zum selbsttätigen Zurückziehen der Backen nach jedem Schnitte versehen sein.
Vor dem Beginn des Arbeitsvorganges wird der Gewindeschneidkopf entriegelt und in die aus Fig. 1 und 2 ersichtliche gestrichelte Lage gebracht. Der angelenkte Anschlag t wird nach einwärts vor das Drehstahlgehäuse gedreht und die zu bearbeitende Stange wird durch den Spindelkopf hindurchgeschoben, bis sie gegen den Anschlag i anstösst, und hierauf in dem Spannfutter festgeklemmt. Nunmehr wird der Anschlag i zurückgedreht und die Stange durch die Buchsen in den Bereich der Drehstähle vorgeschoben und durch diese bearbeitet. Nach beendigtem Abdrehen wird die abgedrehte Stange zurückgezogen, der Gewindeschneidkopf wieder in die Lage vor das Stichelhaus achsial zu demselben zurückgeschwungen und sodann das Gewinde geschnitten.
Die durch die vorliegende Erfindung erziehen technischen und wirtschaftlichen Vorteile bestehen darin. dass die zu bearbeitende Stange während der Dreharbeit um die Breite des Gewindeschneidkopfes weniger weit aus dem Spannfutter herausragt ; dementsprechend erhöht sich der Widerstand der zu bearbeitenden Stange gegen Durchfedern, und andererseits verringert sich der Materialverlust, den jedesmal das letzte Ende der stange darstellt, das nicht mehr ver arbeitet werden kann.

EMI2.1
Sleeve j (Fig. 3).
The cutting head B can be provided in the usual way with devices for processing in two sections (fine cut and rough cut) and for automatic retraction of the jaws after each cut.
Before the start of the working process, the thread cutting head is unlocked and brought into the dashed position shown in FIGS. 1 and 2. The hinged stop t is turned inwards in front of the turning steel housing and the rod to be machined is pushed through the spindle head until it hits the stop i, and then clamped in the chuck. Now the stop i is turned back and the rod is advanced through the bushings into the area of the turning tools and processed by them. When the twisting is complete, the twisted rod is withdrawn, the thread cutting head is swung back axially to the position in front of the burin house and the thread is then cut.
The technical and economic advantages brought about by the present invention are therein. that the bar to be machined protrudes less from the chuck during the turning work by the width of the thread cutting head; accordingly, the resistance of the rod to be processed against deflection increases, and on the other hand, the loss of material, which is the last end of the rod that can no longer be processed, is reduced.
** WARNING ** End of DESC field may overlap beginning of CLMS **.
